Why Ohio homeowners should know it
R-22 and R-410A are the two refrigerants Ohio homeowners are most likely to hear about. R-22 was phased out years ago and is now expensive and increasingly scarce — repairing an R-22 system can quietly cost more than replacing it. R-410A is the modern standard but is itself being replaced by lower-GWP refrigerants such as R-32 and R-454B.
When an HVAC tech recommends replacement instead of repair, refrigerant type is often the real reason. Ask which refrigerant the existing system uses and which refrigerant the replacement quote assumes.

Refrigerant transition is ongoing
The industry is moving past R-410A. A new system quoted in 2026 may already be on R-32 or R-454B; that is normal.
